Refresh ASP.NET Role Provider

由 我只是一个虾纸丫 提交于 2019-12-07 12:16:14
问题 simple question... Given I have an ASP.NET site, which uses a [custom] RoleProvider, Is there any way in which I can somehow "refresh" the provider without forcing the user to log out of the site and log back in? I'm looking for something that would be akin to a fictional method Roles.Refresh() Specifically, I am looking at this for if an administrator changes a user's roles, the user sessions could maybe refresh themselves every 10 minutes or something. 回答1: I assume you have something like

Refreshing Windows program when other users make changes?

由 删除回忆录丶 提交于 2019-12-07 11:58:54
问题 Scenario: 4 users launch separate instances of the same client program (Winforms) that is connected to a database based To-Do list. The first user selects the 3rd To-Do list item. How do I update/refresh the other 3 users screens to reflect that item #3 is no longer available? My thought was a table that contains the last update date-time stamp. Then a timer would check every few seconds to see if there have been any changes. UPDATE1: Thanks to all - there are definitely a number of valid

Asp.Net Button Event on refresh fires again??? GUID?

由 蓝咒 提交于 2019-12-07 09:52:34
The obvious issue here is that on refresh a button event is recalled and duplicate posts are created in the database. I have read other questions on this site about the very same issue. Apparently the answer is for every post create a GUID and check to make sure the GUID is unique? I am not really sure how to implement this. Does that mean on refresh, it will try and create a duplicate post with the same GUID? How do you implement a GUID into your database? Or if this is not the answer, what is? Thank you! The idea is that you create a unique number for the form, and when the form is posted

Auto Refresh document title?

由 不羁的心 提交于 2019-12-07 08:20:30
问题 I have tried many ways to have the page title automatically update every 3 seconds so the title can display how many unread messages they have. Here is what I have tried: setInterval(function() { document.title = "<?php echo $inboxcc; ?>"; }, 3000); and $(function() { setInterval(function() { $(this).attr("title", "<?php echo $inboxcc; ?>"); }, 3000); }); But none of them work. 回答1: This approach won't work. Your PHP statement will execute once on the server-side, so no matter what you do in

问题 How can you make Dartium automatically reload your web client application whenever a change is made to the source files? Related: How do I make Firefox auto-refresh on file change? 回答1: EDIT: You can also skip all this and simply hit CTRL+R in the Editor.

How to dynamically refresh a .NET databound repeater control

由 不问归期 提交于 2019-12-07 01:10:27
问题 I have a .NET repeater control that is data-bound to a List. As part of the Repeater's Item Collection , I have a "Remove Button" that effectively removes this current List element. This works, in code-behind I can successfully remove an item from the datasource of the Repeater . My problem is this : when I reset the updated datasource and call MyRepeater.DataBind() again, the Repeater interface does not refresh with the Item removed. I am looking for the event to essentially redraw or
